Hello,

 

I also have the same problem from 13.09.2019.

Is there any other solution avaiable other than replacing the sub boards?

 

Thank you.

My mobile is on its way to the lab so I hope I will soon know what's going on with it.

Maybe a factory reset solves the issue, if you want, you can try and share your findings.

Make sure to give it a day or two after resetting to make sure it's not there anymore.

Related to car chargers. Since I stopped using my car charger issue has stopped. 

It has taking a few day of using factory charger but it has solved my issue for the moment.

 

DO NOT USE 1.0amp or 2.1amp charger.

 

Go to samsung spend the money for a proper charger and protect the phone rather then damage it and say its Samsung's fault. 

 

Although I do think that Samsung should put a press release or at least a post about this. So far it's the community doing all the work. I had faith in you guys cause of my s3 I had for almost 10 years. I still use to this day lol.

 

Dont let me down samsung come on

 

Now did I have this issue prior to the update, no definitely not. So I do think the update has confused some software program but since I stopped with the car charger it stopped prompting these messages and my screen stays off 95% of the time. Other 5% is the light sensor when it pulls out my pocket or lighting changes.

Plus in your usb cable from the factory charger it will help but not stop this. Continue to charge on factory wall charger. Do this for a few days skip your car charger. See if any changes, also turn your phone off overnight to allow the board to get rid of any built up energy In the componants

Same exact problem here. Contacted my shop and they said it will take atleast 3w to get a check done (send to samsung etc). I cant really miss my phone for 3w but the problem is to annoying to ignore. The battery looks also ruined from the quick draining for me..

Hi guys,

 

Just started having the same problem (22nd september) no clue what to do. Has anyone tried a factory reset? Not ideal but if it fixes the issue then I'd be willing

Mine was in the lab, they said there was a bit of corrosion so they replaced the USB port and now it's ok. Because it was on a small part it will be fixed under warranty.

 

I ask how come and they said it can be moisture, it can be the charging head that connects to the phone, etc etc... I have a mobile phone for more than 20 years now and never had nor heard about this issue.

 

I wonder if something is bad with the phone design that caused this issue but without Samsung checking this, all we have is this discussion.
